Objective: Abortion clinic visits represent an important intervention point to prevent repeat unintended pregnancy. This study identifies factors associated with less effective contraceptive use 12 weeks post-abortion.

Methods: 114 women, aged 18 years or older, completed a baseline survey on the day of their elective 1st or 2nd trimester surgical abortion at the Atlanta Women's Center. 50 women (44%) completed an online follow-up survey 12 weeks later and were included in this analysis. Bivariate and multivariate logistic regression models assessed associations between demographic and reproductive health factors and use of less effective contraception (defined as no method, condoms, withdrawal, and natural rhythm methods) versus more effective contraception (defined as oral contraceptives, ring, patch, injectibles, IUD, implant, and sterilization) at follow-up.

Results: Most women (96%) reported resuming sexual activity at the time of follow-up. Seventeen women (34%) reported using less effective contraception, which was significantly associated with high school education or less (adjusted risk ratio, aRR= 2.80, 95% confidence interval (CI): 1.53 - 5.13) and not receiving a contraceptive method or prescription on the day of their abortion visit (aRR = 4.52, 95%CI: 1.55 - 13.19). The association between a history of prior abortion and less effective contraception trended toward significance (aRR=1.85, 95%CI: 0.91 - 3.78).

Conclusions: Over one third of women are at increased risk for unintentional pregnancy three months post-abortion due to less effective contraceptive use and resumed sexual activity. Education and abortion history may play an important role in more effective contraceptive use post-abortion. Immediate provision of contraceptives during the abortion visit is strongly associated with more effective contraceptive use following the procedure.
